CC -!- FUNCTION: Serine protease which, by cleaving and activating CC prophenoloxidase (PPO1) after immune challenge, plays an essential CC role in the melanization immune response to septic wounding CC (PubMed:16256951, PubMed:16322759, PubMed:19071960, CC PubMed:24260243, PubMed:16861233). May function in diverse Hayan- CC dependent PPO1-activating cascades that are negatively controlled CC by different serpin proteins; Spn27A in the hemolymph and Spn77BA CC in the trachea (PubMed:18854145, PubMed:24260243, CC PubMed:16322759). Important for the innate immune response to CC fungi (PubMed:16861233). Regulation of melanization and PPO1 CC activation appears to be largely independent of the Toll signaling CC pathway (PubMed:16861233). {ECO:0000269|PubMed:16256951, CC ECO:0000269|PubMed:16322759, ECO:0000269|PubMed:16861233, CC ECO:0000269|PubMed:18854145, ECO:0000269|PubMed:19071960, CC ECO:0000269|PubMed:24260243}. CC -!- SUBUNIT: Interacts with Spn27A. {ECO:0000269|PubMed:24260243}. CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:24260243}. CC -!- DEVELOPMENTAL STAGE: First detected in stage 11 embryos, in cells CC close to the gnathal region. At stage 13, expressed in numerous CC cells that are dispersed throughout the embryo. During CC organogenesis predominantly expressed under the cuticle in the CC proventricular zone close to the hindgut. In L3 larvae, expressed CC in the lymph glands, the hematopoietic organ that flanks the CC dorsal vessel and in mature hemolymph crystal cells that appear in CC clusters attached to diverse organs. CC {ECO:0000269|PubMed:16256951}. CC -!- INDUCTION: Up-regulated after wounding. Levels are higher with CC septic wounding, using either Gram-negative or Gram-positive CC bacteria. {ECO:0000269|PubMed:16256951}. CC -!- DISRUPTION PHENOTYPE: RNAi-mediated knockdown is semi-pupal CC lethal, with 50% of pupae dying at the late pupal stage or during CC eclosion (PubMed:16861233). Adults display impaired melanization CC at the site of septic infection (septic injury) using either Gram- CC negative or Gram-positive bacteria (PubMed:16256951, CC PubMed:16861233, PubMed:19071960). Reduced survival, PPO1 activity CC and induction of the antimicrobial peptide Drs following septic CC injury using the fungus B.bassiana (PubMed:16256951, CC PubMed:16861233). Septic injury with various bacteria reduces CC survival (L.monocytogenes, S.typhimurium and S.aureus) and in some CC cases decreases (E.faecelis) or increases bacterial growth CC (L.monocytogenes, S.typhimurium and B.cepacia). Aseptic injury CC reduces survival (PubMed:19071960). Aseptic wounding has no effect CC on survival (PubMed:22227521). Significant increase in survival CC after immune challenge with S.pneumoniae although there is no CC increase in melanization (PubMed:19071960). No effect on the CC survival following infection with various bacteria (E.coli, CC B.cepacia and E.faecelis) (PubMed:19071960). No induction of the CC antimicrobial peptides Drs and Dpt following infection with CC E.carotovora (PubMed:16861233). {ECO:0000269|PubMed:16256951, CC ECO:0000269|PubMed:16861233, ECO:0000269|PubMed:19071960, CC ECO:0000269|PubMed:22227521}. CC -!- SIMILARITY: Belongs to the peptidase S1 family. CC {ECO:0000255|PROSITE-ProRule:PRU00274}.
